Horizontal retractable running board with high load capacity

Abstract

A retractable running board (A) comprising at least one supplementary step that facilitates getting in/out of a vehicle (B) for the passengers, e.g. in vehicles (B) with high ground clearance, at least one driving member supplying the driving force required by the system, at least one drive shaft, at least two flanges in at least one of which said driving shaft is embedded, at least two levers that are engaged with said flanges and capable of performing rotational movement in y axis (y) perpendicular to the ground upon being actuated by the drive shaft, at least one intermediate lever, and at least two step brackets which are secured in said supplementary step and which, at the other end of the lever which is fixed to the flange, are capable of performing rotational movement in y axis (y) perpendicular to the ground relative to each other.

The invention claimed is: 
     
       1. A retractable running board (A) comprising a supplementary step ( 21 ) that facilitates getting in/out of a vehicle (B) for the passengers in public transportation vehicles (B) for transporting passengers, passenger cars, and vehicles (B) with high ground clearance; characterized by:
 at least one driving member ( 1 ) supplying the driving force required by the system, 
 at least one drive shaft ( 7 ) transferring the driving force received from the driving member ( 1 ) to the system, 
 at least two flanges ( 13 ) in which the driving shaft ( 7 ) is embedded and which assist the system to be mounted in the vehicle (B), 
 at least two levers ( 25 ) that are engaged with the flanges ( 13 ) and capable of performing rotational movement in y axis (y) perpendicular to the ground being actuated by the drive shaft ( 7 ), 
 step brackets ( 22 ) which are fixed on the supplementary step ( 21 ) and capable of performing rotational movement in y axis (y) perpendicular to the ground relative to each other at the other end of the lever ( 25 ) which is not fasten to the flange ( 13 ), and 
 an engine connecting piece ( 32 ) located between said driving member ( 1 ) and supplementary step ( 21 ) and an angle ( 33 ) mounted to the back surface of the vehicle mounting bracket ( 4 ). 
 
     
     
       2. The retractable running board (A) according to  claim 1 , comprising at least one intermediate lever ( 27 ) which is engaged between the levers ( 25 ) and ensures synchronization by transferring movement therebetween, and which is located at a different angle than the connection angle of the supplementary step ( 21 ) such that the instability of the two levers ( 25 ) at the central position during movement will be prevented. 
     
     
       3. The retractable running board (A) according to  claim 1 , comprising at least two vehicle mounting brackets ( 4 ) connecting the flanges ( 13 ) to the vehicle (B). 
     
     
       4. The retractable running board (A) according to  claim 1 , comprising a cap ( 6 ) thereon for protection against external factors such as water, mud, etc. in case the flange ( 13 ) is not provided with the driving member ( 1 ). 
     
     
       5. The retractable running board (A) according to  claim 1 , comprising a stopper ( 23 ) limiting the rotational movement formed on the flange ( 13 ). 
     
     
       6. The retractable running board (A) according to  claim 1 , comprising a connection cable ( 28 ) for supplying the required power to said driving member ( 1 ). 
     
     
       7. The retractable running board (A) according to  claim 1 , comprising a bracket cap ( 30 ) located at the lower portion of the step bracket ( 22 ). 
     
     
       8. The retractable running board (A) according to  claim 1 , comprising an engine cap ( 31 ) which is fixed on the lower portion of the connection axis of said lever ( 25 ).
